Cells infected with Sindbis virus (SV) make two positive-strand RNAs, a genomic-length RNA (G) RNA and a subgenomic (SG) RNA. In cells infected with SVstd, and in general in cells infected with wt alphaviruses, more SG RNA is made than G RNA. How the balance between synthesis of G RNA and SG RNA is regulated is not known. SVpzf and SVcpc are nsP4 mutants of SV which, in mosquito cells, make mor...
Rotavirus (RV) is the major cause of severe gastroenteritis in young children. A virus-encoded enterotoxin, NSP4 is proposed to play a major role in causing RV diarrhoea but how RV can induce emesis, a hallmark of the illness, remains unresolved. In this study we have addressed the hypothesis that RV-induced secretion of serotonin (5-hydroxytryptamine, 5-HT) by enterochromaffin (EC) cells plays...
Coronaviruses are the largest RNA viruses, and their genomes encode replication machinery capable of efficient replication of both positive- and negative-strand viral RNAs as well as enzymes capable of processing large viral polyproteins into putative replication intermediates and mature proteins. A model described recently by Sawicki et al. (S. G. Sawicki, D. L. Sawicki, D. Younker, Y. Meyer, ...
Herein we present the synthesis of a novel type of peptidomimetics composed of repeating diaminopropionic acid residues modified with structurally diverse heterobifunctional polyethylene glycol chains (abbreviated as DAPEG). Based on the developed compounds, a library of fluorogenic substrates was synthesized. Further library deconvolution towards human neutrophil serine protease 4 (NSP4) yield...
We have previously shown that very few rotavirus (RV)-specific T cells that secrete gamma interferon circulate in recently infected and seropositive adults and children. Here, we have studied the interaction of RV with myeloid immature (IDC) and mature dendritic cells (MDC) in vitro. RV did not induce cell death of IDC or MDC and induced maturation of between 12 and 48% of IDC. Nonetheless, RV ...
